The trio are cleaning out the gutters of the house. Mordecai picks up the dirty leaves and puts them into a bucket. "Augh! This is the worst." He said. "Tell me about it." (Y/n) agreed. "I don't know, I kind of like it up here. The world seems different at this height. It makes me feel like a giant!" Rigby said, then he pretends to roar. "What? Look, we're not up here to enjoy the view, so will you just come and help us clean these gutters?"

Mordecai asked. "I'm helping, I'm holding the hose. Look, I'm taking a giant leak." Rigby positions the hose to his crotch, turns it on and pretends to pee. "Ohhhhh." "Gross, dude." (Y/n) said. "Yeah, well, you don't need those gloves to hold the hose." Mordecai holds up his hands. "Look at this dude. Come on, let me wear them!" He said. "Sorry man, you should have thought about that before you threw paper, and lost to my scissors." Rigby said. "Whatever. Just hose this stuff off." (Y/n) said. Rigby hoses the leaves out of the gutter. A cassette tape is launched into the air and hits (Y/n) in the head. "Ow!" The tape falls to the ground.

"What the heck?!" She asked. "Uh, sorry, (Y/n)." Rigby said. Mordecai picks it up. "Weird, it's a tape. Wonder what it's doing up in the gutter." He said. "Maybe it fell out of a plane." Rigby said. "Nah, it's probably just trash. Give it here, I wanna see how far I can chuck it." (Y/n) said as she grabs it. "Wait!" Rigby said. "What?" (Y/n) asked. "Don't you wanna see what band it is?" Rigby asked. "Oh, okay." She wipes dirt off of tape to reveal the words "Solid Bold" "Solid Bold? Augh, it's that single of that summertime song." She said. "Summertime Loving: Loving in the Summer (Time)"?" Rigby asked. Mordecai looks at the tape. It says exactly what Rigby said.

"Yeah." He said. "Gimme! Gimme! Gimme!" Rigby grabs the tape. "Aw, this is my jam right here!" He said. "What? This song sucks." (Y/n) said. "Agreed." Mordecai said. "Nah, you were all into it too, I remember., Mordecai." Rigby said. "Yeah, just for that one summer in junior high and then I realized how lame it was." He replied. "Whatever, man. Once we pop this into the stereo,

all the good memories will come flooding back, and you'll see. You'll see who's jam it is." Rigby said. "I'm not listening to that trash." Mordecai said. "Me either." (Y/n) crosses her arms. "You  two need to get your mind out of these gutters, and into the summer." Rigby said. "Fine, but only because I want to take a break." (Y/n) said. Rigby puts the tape in the stereo, and the song starts. "It's summertime, and you know what that means. Gonna head down to the beach, gonna do some beachy things. It's summertime and it feels just right." "Ugh!" (Y/n) instantly covers her ears.

"Gonna gather all my friends and we'll party through the night. It's summertime, lo-o-ovin'. Lovin' in the summertime. (It's summertime) Summertime lo-o-ovin'. Baby, why can't you be mine?" "Okay, this song's lame." Rigby said. "We told you, man." Mordecai said. "Summertime..." Rigby ejects the tape and throws the tape into the garbage. "Man, I guess some stuff just doesn't hold on." Rigby said. "Now you're making sense, and now I'm making snacks." Mordecai said. Later the trio are eating sandwiches. "It's summertime..." Rigby continues to eat. "Lo-o-ovin'..." he eats again. "Loving in the summertime." He sung. "What are you doing?" (Y/n) asked in confusion. "What?" Rigby asked, clearly oblivious.

"You're singing that song." Mordecai said. "I am?" He asked in surprise. "Yes, please stop. It's annoying." (Y/n) said. "I guess it's pretty catchy." Rigby said. Rigby confusedly eats his sandwich. Later the trio are cleaning the gutters. Rigby takes a leak like before. "Summertime lo-o-ovin'. Baby, why can't you be mi-" Rigby sung. "Dude!" Mordecai said. Later the trio are watching television, and Rigby is still singing. "Gonna head down to the beach, gonna do some beachy things." "Dude!" (Y/n) said. Some more time later the trio are walking in the park, Rigby sings again, however, Mordecai and (Y/n) are annoyed by this song, unable to take it anymore. "It's summertime lo-o-o-" Rigby continues. the duo blow up in annoyance. "Dude! Quit it!"

Mordecai shouted. "Yeah, seriously! You've been singing that obnoxious song all day, it's driving me crazy!" (Y/n) shouted. "I'm sorry, I can't help it, it's stuck in my head, and I can't get it out." Rigby said. "Well, for our sanity and yours, we gotta get that song outta there." Mordecai said. "Yeah, okay." Rigby said. Later the trio are in Mordecai and Rigby's room. "Okay, okay. I've got the perfect solution: Brain Explosion." Mordecai said. "What? You can't explode my brain. That's gotta be illegal."

Rigby said, and (Y/n) chuckles. "No, it's a band, idiot." She said. Rigby glares at her for a moment. "Oh, never heard of them." Rigby said. "They're not that good." (Y/n) said. "What? You don't know what you're talking about, (Y/n). But trust me, these guys are like real, real musicians. Just listen to some of this, and It will throw that poppy trash music right out of your head." Mordecai puts the CD in the stereo. The CD plays a triphoppy song, and Rigby and (Y/n) share a look.
"Wait, wait... Aw man, that's like the best part." Mordecai glares at Rigby sleeping. "Rigby!" He wakes up startled. "Lovin' in the summertime. What? Ah, I think your song just put me to sleep." He said, and (Y/n) chuckles. "Told ya." She said. Mordecai turns the stereo off. "Man, you two have no taste in music." He said. "Look, all I know is that this song is still stuck in my head." Rigby said.

"Alright, well, what if we sit down and listen to the entire summertime song beginning to end." Mordecai retrieves the summertime cassette from the trash. "That way your brain'll have closure and then it can move on." He puts the cassette into the stereo. "It's summertime and you know what that means. Gonna head down to the beach, gonna do some beachy things." The music plays. "I can't stand this, I'm gonna wait outside." Mordecai said. "Meet you out there Rigby." (Y/n) follows him out. "It's summertime and it feels just right. Gonna gather all my friends and we'll party through the night..."

Time Skip

Rigby is sitting on the bed, song is still playing. "Summertime lo-o-ovin'. Baby, why can't you be mine?"

Time Skip

Rigby is lying against the nightstand, the song is still playing. "Summertime lo-o-ovin'. Lovin' in the summertime." Rigby turns the tape off, Mordecai opens the door and he and (Y/n) come in. "Well, did it work?" Mordecai asked. "I think it worked, but I can't be sure. So maybe I should listen to the song a little bit more." Rigby said in the tune of the song. (Y/n) groans and face palms. "Oh no..." she said. "Aw, man! It's even worse now. Time to take a different approach." Mordecai said. The trio do various things to get the song unstuck, like sticking Rigby's head in a toilet,

using loud objects and finally Muscle Man hitting Rigby on the head with a broom. Rigby takes his helmet off. "Wait. Stop. Stop. It's not working. The stupid song's still stuck in my head." He said. "You have a song stuck in your head?" Muscle Man asked. Rigby throws the helmet at Muscle Man, much to his annoyance. Later the trio are in the duo's bedroom. "Guys, we're running out of options here. Let's see." (Y/n) said. The song starts playing. "Dude, turn it off, I'm trying to think." Mordecai said. "Dude, stop playing the tape we've already tried-" (Y/n) began. She and Mordecai turn and gasp. Rigby is floating with a purple beam coming out of his mouth and pupils dilated. He suddenly goes back to normal and the song stops playing. "Dude, what's wrong with you?!" Mordecai asked. "I don't-" Rigby floats again, then goes back to normal. "Know! I can't-" he floats again, then once again goes back to normal.

"Control it!" Rigby floats again. "We gotta find Skips." (Y/n) said. The trio go to see Skips. "Yeah, I've seen this before. Hold still." Skips holds floating Rigby and punches him. "Oww! What was that for?!" He asked. "You're not thinking about the song anymore, are you?" Skips asked. Skips and Mordecai laugh, until (Y/n) glares at them with causes them to stop. "Look, seriously, I don't know what's wrong with you. Just sleep it off, you'll probably forget about it in the morning." Skips said.

Time Skip

Rigby is now dreaming. The background is empty. Rigby walks around. "Hello?" He asked. Large speaker emerges from the ground playing the song. Rigby runs and another speaker emerges. "Get out, get out!" Rigby screams, and digs into his ear and pulls out the cassette and throws it far away. He laughs victoriously but suddenly, a giant shadow emerges and runs towards Rigby. Rigby wakes up. "The song. It's gone!" Rigby runs to Mordecai who is asleep. Mordecai! Mordecai!!" He shouted. "Huh? What's up?" He replied. "The song's not in my head anymore!" Rigby said.

"That's awesome, dude. Now we never have to hear that dumb song again." Mordecai said. Suddenly, they hear the song again. Mordecai gasps, prompting Rigby to turn around. To Mordecai's and Rigby's horror, they realize that the situation has gotten much worse than they thought. Although, they were able to get the tape out of Rigby's head, but now with the cassette free, it manifested itself into physical form. Now he's a large cassette with stick arms and legs and red sunglasses. "What the heck is that?" Mordecai asked. The giant cassette continues to play.

"I have no idea what I'm looking at." Rigby said, horrified. The music ended up being so loud it woke up (Y/n) and she knocks on the door, catching the duo's attention. "Guys? What's gong on? Why are you blasting that horrible-" she cut herself off as she saw what they were seeing. Her eyes were wide with horror. "What the hell?!" She asked. "What is this?!" She asked. "I think the song must've left his head and manifested itself into a physical form." Mordecai replied. "Well, does it have an "Off" switch?" Rigby asked. "I don't know." Mordecai said.

"It better." (Y/n) said. (Y/n) marches over to it. "Hey dude." It turns to her. "Shut up!" She tries to swat at it, but it quickly dodges her and sends her flying. "Oof!" "(Y/n)!" Mordecai quickly helps her up. "You okay?" He asked. "Yeah..." she said. "Hey!" Rigby runs over to it angrily. "Knock it off! Dude, come on, quit it! Seriously, man! I'm sick of this song!" Rigby shouted. It drums on Rigby's head.

"Get off!" Rigby tackles the cassette and goes right through it. "Oh my gosh, it's a ghost tape!" He shouted. "Great..." (Y/n) mumbles sarcastically. "Dudes, calm down. It's not a ghost. It's just music. You can't touch music. But music can touch you." Mordecai said. "Clearly." (Y/n) said. "Oh, barf. How do we get rid of it?" Rigby asked. "I don't know. If we just ignore it, it'll probably just go away." Mordecai said. The trio do everyday activities with the cassette dancing around them. Everyone, especially Benson, gets annoyed, Benson leaves in annoyance as the others walk away extremely irritated.

"Ugh! That's it, we gotta do something about this." (Y/n) said. "What can we do? He's unstoppable!" Rigby said. "We gotta fight fire with fire." (Y/n) said. "(Y/n), hello. Fire's just gonna go right through him." Rigby said. "No dude, we gotta battle him with our own song." Mordecai said. "What?" Rigby asked. "We're gonna write the cheesiest, most repetitive, catchiest song ever, and we'll see how he likes it." (Y/n) said. "Aw, snap!" Rigby said. "And that's the perfect title!" Mordecai said. The cassette comes running down the hall then walks through the wall.

"Come on!" (Y/n) said. The trio leave and run into Pops. "Pops!" They said. "We need you to distract the "Summertime" Song." Mordecai said. "But I can't stand that song." Pops said. "Nobody can, but we're gonna get rid of it for good. But we need you to buy us some time, so just go dance with him and pretend like you're having fun." (Y/n) said. "Alright, then." Pops said. "Thanks, Pops." (Y/n) said. The trio run off. "But I'm not going to use my best dance moves!" Pops said.

The cassette comes up to Pops, and he starts dancing nervously. The trio open the garage door and walk up to the keyboard. "Okay, song, song..." Mordecai plays some notes. "Okay, we'll just repeat that. And lyrics, go." He said. "Uh, Summertime loving." Rigby said. "No dude, it has to be different from that one." (Y/n) said. "She's right, give her something she can use. What do you like?" Mordecai asked. "Partying." Rigby said. "Yeah, uh huh. Uh huh."

(Y/n) said as she writes that down. "Macaroni. Oh, naps! I love naps." Rigby said. "Alright, good enough." (Y/n) said, as she kept writing it down. "Okay, I'm here. And I brought my bass." Skips said. "Wait. How did you..." Mordecai asked. "I know everything, remember?" Skips asked. "Whoa..." the duo said. "Okay, that isn't creepy at all." (Y/n) said sarcastically. "Nah, I'm just yanking you.

I was on the can and I heard your plan." Skips said. "Ugh!" The trio said. "Skips is a poet, I didn't know it." (Y/n) said sarcastically, and he chuckles, but then gets serious. "Let's roll." "Pops, come in, Pops." (Y/n) said on a walkie talkie. "Yes, hello?" He asked. "I need you to lure the "summertime" song outside, okay?" (Y/n) asked. "Yes, okay. The party continues this way, my friend." Pops said. Pops and the cassette run down the stairs. (Y/n), Mordecai, Rigby and Skips are setting up. "Okay, get ready guys." Mordecai said. "Wait up! Don't start the party without us, fellas." Muscle Man said. "Whoa! Muscle Man, you play something?" (Y/n) asked.

"Yeah, Muscle Man blows a mean piece of brass." Skips said. "Yeah." He plays some notes on his trumpet. "And you know who else blows a mean piece of brass?" He asked. "Not now!" (Y/n) hissed. "Here they come!" Rigby said. "Pops!" Mordecai said. Pops runs to the keyboard. Rigby taps the tambourine. "One, two, three, four!" He shouted. "Aw, snap! Aw, snap! Come to our macaroni party and we'll take a nap. Aw, snap! Aw, snap! Come to our macaroni party and we'll take a nap. Aw, snap! Aw, snap! Come to our macaroni party and we'll take a nap.... " everyone sung together.

The cassette hits back with sound waves by playing the song. The waves drown them out. "Louder! Come on!" (Y/n) shouted. "Aw, snap! Aw, snap! Come to our macaroni party and we'll take a nap. Aw, snap! Aw, snap! Come to our macaroni party and we'll take a nap." Their sound waves knock the cassette over. The cassette shoots a purple beam and they shoot out a green one. Two giant musicians appear in the sky and fight. "Aw, snap!" They get slower.

"Aw, snap!" Even slower. "Aw, snap!" The combined sound waves knock down the Snack Bar and shatter Benson's window. Benson looks out his window and runs out the door. The cassette's giant musician overpowers their giant musician. "He's too strong!" Rigby shouted. "No, we can do it!" Mordecai collapses and sees Benson driving the golf cart towards them. "Oh crap, Benson!" (Y/n) said. Benson stops the cart. "Unbelievable!" He shouted.

"Look Benson, we didn't mean-" (Y/n) began. Benson gets on top of the cart. "You guys forgot the most important thing about writing a catchy song." He reveals a drum set on top of the cart. "Whoa!" The trio said. "It's gotta have a beat." Benson begins drumming impressively. Benson taps his drum sticks and they resume playing. "Aw, snap! Aw, snap! Come to our macaroni party and we'll take a nap."

Their giant musician begins overpowering the cassette's giant musician. "Aw, snap! Aw, snap! Come to our macaroni party and we'll take a nap. Aw, snap!" Their giant musician smashes the cassette's giant musician, the cassette explodes. "Man, Benson, that was amazing. I didn't know you could play the drums like that." Mordecai said. "Well, it's a funny story." Benson said. Rigby's pupils dilate. "Aw, snap! Aw, snap! Come to our macaroni party and we'll take a nap. Aw, snap! Aw, snap! Come to our macaroni party and we'll take a nap." He sung, much to their dismay and horror. "Nooo!" Everyone shouted.
